Methylcyclopentadiene is any of three isomeric cyclic dialkenes with the formula C 5 MeH 5 (Me = CH 3).These isomers are the organic precursor to the methylcyclopentadienyl ligand (C 5 H 4 Me, often denoted as Cp′), commonly found in organometallic chemistry.
NiCl 2 + 2 NaC 5 H 5 → Ni(C 5 H 5) 2 + 2 NaCl. Organometallic complexes that include both the cyclopentadienyl anion and cyclopentadiene itself are known, one example of which is the rhodocene derivative produced from the rhodocene monomer in protic solvents. [14]
2,3-pentadiene, H 3 C−CH=C=CH−CH 3, with two enantiomers (R and S). [5] It and 1,2-pentadiene are the least common isomers of pentadiene. Well known derivatives containing pentadiene groups include hexadienes , cyclopentadiene , and especially three fatty acids linoleic acid , α- linolenic acid , and arachidonic acid as well as their ...
1,2,3,4,5-Pentakis(4-butylphenyl)-1,3-cyclopentadiene is an organochemical compound from the diene group and a cyclopentadiene derivative. The anion of this compound is used as a sterically demanding ligand, often abbreviated as Cp [BIG] , in the organometallic chemistry of sandwich compounds .
Some dienes: A: 1,2-Propadiene, also known as allene, is the simplest cumulated diene. B: Isoprene, also known as 2-methyl-1,3-butadiene, the precursor to natural rubber. C: 1,3-Butadiene, a precursor to synthetic polymers. D: 1,5-Cyclooctadiene, an unconjugated diene (notice that each double bond is two carbons away from the other). E ...

The fire is more than 84% contained as of Sunday. It has so far burned more than 23,440 acres and flare-ups have continued to spark nearly three weeks later.
Di-tert-butylcyclopentadiene is an organic compound with the formula (Me 3 C) 2 C 5 H 4, where Me = methyl.It is a colorless liquid that is soluble in organic solvents. The compound is the conjugate acid of the di-tert-butylcyclopentadienyl ligand, (Me 3 C) 2 C 5 H 3 − [1] (sometimes abbreviated Cp ‡−).
